Air compressor heat exchangers are widely used in petroleum, chemical, light industry, medicine, energy and other industrial production. However, after long-term operation of the heat exchanger, dirt will form inside. The accumulation of dirt will reduce the cross-section of the internal passage of the air compressor heat exchanger, or even block it, resulting in insufficient cooling water flow and reduced pressure drop, resulting in shutdown, shutdown, and even safety accidents such as cracks, bulges, and pipe bursts. So, what is the reason for the fouling of the air compressor heat exchanger? The following is the answer from the air compressor manufacturer.

Reasons for fouling of air compressor heat exchanger:

1. Particulate dirt:

The solid particles suspended in the fluid system, such as sand, dust, carbon black, etc., accumulate on the surface of the heat exchanger to form dirt.

2. The dirt produced by the chemical reaction:

Between the heated surface and the fluid, deposits are formed due to auto-oxidation and polymerization reactions, that is, chemical reactions.

3. Corrosion dirt:

Because the fluid is corrosive or contains corrosive impurities, it causes corrosion on the surface of the heat exchanger, and the corrosion products deposit on the surface of the heat exchanger to form dirt.

4. Solidified dirt:

On the supercooled heat exchange surface, the dirt formed by the solidification and deposition of the highly soluble components of the cleaning fluid or multi-component solution.

5. Biological fouling:

It is a kind of viscous deposit formed by microorganisms and their excrement, chemical pollutants, mud and other components on the heat exchange tube wall, called biological fouling.

6. Dirt precipitation:

Heat exchangers are mostly heat exchange systems with water as the heat carrier. When the temperature rises or the concentration is higher, the Ca(HCO3)2 and Mg(HCO3)2 originally dissolved in the water will precipitate out slightly soluble CaCO3 and MgCO3. The precipitated salt adheres to the surface of the heat exchange tube to form scale, and the scale is tightly attached to the surface of the heat exchange tube.

The above is the reason for the formation of fouling in the heat exchanger of the air compressor. If you want to know more about permanent magnet variable frequency air compressor products, please feel free to contact our company, we will be happy to serve you!
